ItemTeacher's management of learning in small groups in science classes( 1993)Established curriculum documents in Victoria recommend group work as an effective teaching strategy but the implementation and management of such groups is poorly understood by many teachers. This study investigated two management strategies which differed in the degree of role attribution amongst group members and the effect of the strategies on communication, behaviour patterns and achievement on a problem solving investigation. Students in three parallel year eight science classes from one school were observed over an eight week period. A low level and a high level management strategy were randomly allocated to each of two classes and used to manage group work. After four weeks the management strategies were exchanged. The third class, which was used as the control, was managed in a way which was more typical of a traditional science class. Randomly selected groups of students from each class carried out a practical problem solving investigation as a pretest, then again at the completion of the first four weeks (phase 1) and again after the completion of the second four weeks (phase 2). Student conversations within groups were recorded and coded to identify levels of communication types. Students' written reports for each test were assessed and scores analysed. Teachers completed an observation schedule to identify styles of leadership and types of group behaviour within each class. It was found that the use of the low level management strategy, in particular, did increase the relative frequency of communication at higher cognitive levels, those of conceptualisations, as compared with the control treatment. Problem solving skills as measured by achievement on the written practical investigation improved over time and there was a significant effect in the area of "making measurements" when the management strategies were used as compared to the control treatment.

ItemStudents, computers and learning : a conversation with the cognitive apprentices and their learning tools( 1998)Wertsch (1991) asserts the mind "extends beyond the skin", that is, it is socially distributed and is a function of activity involving cultural tools. From this perspective the mind is unlimited in the sense that it is developed and inseparable from tools of mediation of which the computer is a corporeal thing that extends out into the material world. The computer as a means of mediation can be invisible yet powerfully influential in shaping thought and communication.. In this small-scale case study in an academic independent school a representative focus group of year 9 students suggests to the Author, their school's computer specialist, that their teachers are not to be providing mediated learning with computers. The students who are the metaphoric "cognitive apprentices" feel the school as an institution has not 'grasped the idea.' Bryson and De Castell (1994, 215) observed that " ... the divisive playing field of educational technology is populated by various teams who are telling altogether different 'true stories,' each having different settings, characters and plots ..." The new age believers and the non believers were not listening to the users. Hargreaves (1996) offered a parallel critical assessment, after Plummer (1983) and Wood (1991), of the use of "voice" in contemporary educational research. He stressed the need for active participant voices outside conventional conversations, from different contexts, different positions and particularly the marginalised. In both educational practice and research, student's voice has frequently been considered " a nuisance; literal noise in the instructional system" (Cazden 1986, 448). However, if teachers and schools as agents of parents and society are to embrace computers as cognitive tools, and accept them into the educational context as a means to gaining one or more educational ends, then there is need to research the voices of the cognitive apprentices on their learning with computers. The collaborative nature of the ethnographic research was grounded in the mutual regard of the researcher and the practitioners (students) as change agents in their own school. Central to the research was the development and exploration of a clue structure to understand how student practitioners saw computers being used in their classrooms. The initial core questionnaire asked the students to position their opinion of the school's , and their teachers' use of computers in the provision of the curriculum on a continuum between; "Are computers instructional tools used by teachers to impart knowledge to you", or, "Are computers used as cognitive tools to afford students' opportunities to construct representations of their knowledge and understandings of the concepts being taught ?

ItemThe evolution of concepts of decimals in primary and secondary students( 1994)This thesis studies children's conceptions about ordering decimals. It builds upon previous work which established three commonly used systematic errors in children's understanding as they encounter decimal notation. Students were categorised according to erroneous rule usage. This work includes a small longitudinal study which showed little change over twelve months in rule usage by an Australian sample of 50 secondary students. The categorising tests were redeveloped to make them suitable for primary students and to have increased reliability. The main study traced the use of rules from Year Four to Year Ten in a sample of 379 students and showed how students with different rules performed on other decimal tasks. It was found that one of the rules, called the whole number rule (in comparing two decimals that with more decimal places is chosen as the larger) was important in earlier years but disappeared with time. The second rule, called the fraction rule (the decimal with fewer decimal places is chosen as the larger), persisted in worrying proportions well into the secondary years and it was shown that significant gaps in knowledge of decimal notation existed which had not corrected themselves with time. The third rule was shown to be not important. Further investigation of a longitudinal nature to examine how individuals actually make the transition to mastery of decimal notation is encouraged by this study.

ItemThe ideas of covariation and rate of change in introductory calculus( 1996)This thesis is a formative evaluation of a new curriculum which has evolved at a Victorian secondary school, with the aim of better preparing students for introductory calculus than has traditionally been the case. The new curriculum focuses on the ideas of the rate of change of the dependent variable and the covariation of the variables using tables of values to examine and emphasise the way that the function changes, before moving to the graphical and algebraic representations. This approach is in contrast to the more traditional curriculum where families of functions are introduced using the algebraic representation, and where the central ideas of change and covariation may be obscured. Because of inherent limitations of this study, it was not possible to produce conclusive evidence; however, the results gave a strong indication that the new approach shows promise for an improved understanding of students studying introductory calculus.

ItemAn evaluation of a short, intensive mathematics program( 1999)This thesis evaluates a short intensive mathematics program for primary and secondary students that was conducted at the University of Melbourne in April 1997. The methodology of the evaluation can be described as action-research: a collaborative investigation where researchers, teachers and students cooperate in order to gain insights into a specific learning environment. This process is conducive to various improvement and modifications that the participants can apply to their respective practices. The primary aim of the thesis was to explore factors affecting the success of such programs and the learning which results. The findings suggest that while mathematical self-esteem is closely associated with mathematical achievement actual changes in mathematical self-esteem might not be easily detectable in programs of such short duration. The strength of the Program seemed to be the 'learning atmosphere' fostered by the instructors as well as in the choice of non-routine tasks. A possible weakness was the lack of clear focus regarding the pedagogical aims of the Program.

ItemGhost stories : an ethnographic journey( 1998)This is an ethnographic study of a school theatre project, 'Ghost Stories'. The study explores what the role and nature of extra curricular theatre is in an independent boys' school. The concept of 'school theatre' is defined as an aesthetically rich, extra curricular event. The study argues that a teacher of 'school theatre' creates learning experiences for students that empower and challenge the politically or economically sanctioned educational culture. The value of school theatre, the role of the teacher, the development of students' artistic and personal skills and the relationship between school theatre and the dramatic heritage is investigated. The study argues that a believable, trustworthy account of the school theatre event needs to incorporate the variety of participant voices. The report is written in the form of a narrative and is told by the drama teacher responsible for the performance project, a male and female student, a teacher assisting in the performance project and a senior member of the administration. The narrative traces the participants' motives in becoming involved in the 'Ghost Stories' performance project, the various perceptions of the value of student devised performance texts, the conflicts within this educational context, culminating in the final night's presentation ceremony. The 'Ghost Stories' performance event challenges the conduct of teaching and learning in this educational context. The study contends that a teacher of 'school theatre is engaged in 'critical pedagogy'.

ItemThe Victorian Certificate of Education : the change process and teacher practice( 1995)There are two key issues in this study. Firstly, to examine the extent to which teacher practice has changed during the first year of implementation of the Victorian Certificate of Education's Year 11 Legal Studies study design - Unit 1 - Criminal Law and Civil Law. The second key issue is to explore the extent to which any change in teacher practice is due to the new course and the manner in which it was implemented. For this study I have used a case study approach with a series of cross-case techniques when analysing the data. Three cases were selected for study. Several different methods of data collection were employed. Specifically, external observation, systematic interviewing, collection and analysis of documents and checklists were used on a regular basis. To develop the cross-case synthesis I adopted cross-site analysis techniques as suggested by Miles and Huberman (1984) in their text Qualitative Data Analysis: A Sourcebook of New Methods. In order to plan this study, an overview of some of the key writings in this area was undertaken. Specifically, key writings on implementation and the process of implementation in relation to teacher practice were reviewed. This process is explored through the examination of several theories and models on implementation. How teachers perceive a change to existing curriculum programmes and the extent to which that curriculum leads to a modification in teacher practice is examined in detail. Particular attention is paid to the range of variables and interventions that can lead to a modification in teacher practice. The major findings and conclusions drawn from this study indicate that the teachers' pedagogical judgments, plans and decisions reflected a reasonably narrow collection of educational goals. These goals were shaped, in the main, by the realities of their classroom environments. The teachers prioritised most matters on a cost benefit ratio. This was particularly evident in relation to the intervention strategies. They also underwent a period of uncertainty about the change which compounded their reluctance to move away from established classroom practice and adopt certain teaching techniques that complemented the flexible nature of the study design. Decisions regarding teacher practice, therefore, were orientated around 'tried and true' techniques that met a number of preconditions. Specifically the need to balance the competing academic needs and interests of their students; student willingness to cooperate and feel comfortable with the teaching style adopted; perceptions of what the new content and assessment offerings required, and the limitations of time dominated their decision-making process. The end result was a general reluctance to discard established methods of teacher practice given these classroom 'realities'. The major findings, therefore, indicate that an educational change in terms of a modification to teacher practice was difficult to achieve.

ItemA study of student perceptions of difficult genetics concepts( 1990)The teaching and learning of genetics has interested many researchers in recent years. Some authors have used genetics as a topic which exemplifies broader curriculum issues, while others have studied problems which are inherent to the topic. However, all have acknowledged that genetics is a significant subject because of its scientific importance and social relevance. This thesis reviews some broad issues of science teaching in order to place genetics within a science framework. Problems specifically pertinent to a genetics curriculum are then focussed upon. Three major areas of research in science learning are discussed. These are meaningful learning, concept mapping and problem solving. Meaningful learning is not just "getting the right answer", but occurs when new concepts are linked to existing ones. Many researchers therefore stress the usefulness of concept mapping as a tool to encourage meaningful learning. Problem solving is a special case of meaningful learning and is also recognised as a skill applicable to novel situations. Research into genetics teaching can be divided into three categories. These are difficult concepts, sources of misconceptions and problem solving strategies. There is general agreement about the concepts which are most difficult for students to understand. All authors emphasise the importance of associating meiosis with classical genetics. Valuable work has provided lists of difficult terminology and concept maps of suggested teaching sequences. It is clear that some textbooks are confusing and reinforce misconceptions that students hold. Studies of problem solving strategies confirm that an expert/novice dichotomy is artificial, rather that a successful/unsuccessful continuum exists. Recent literature indicates that teachers benefit from knowing which genetics concepts students perceive as difficult. Students in both Australia and Britain were surveyed and thirty statements were then placed in rank order of difficulty. These results supported previous research and confirmed the need to view a topic from the learner's point of view rather than just the teacher's standpoint.

ItemA study of religious education in Catholic secondary schools : attitudes of students, content, methodology and gender issues( 1999)The subject of Religious Education (RE) is the one feature distinguishing Catholic Schools from Government Schools. It is a unique subject because its impact on students' lives is long-lasting and important. The factors influencing students' attitudes and perceptions of RE are examined in this study. Two of the main factors researched here include the content of Religious Education lessons and the methodology employed by teachers, as perceived by students. Marked differences in the gender responses of students were observed to be very significant and these are discussed and explored. Recommendations for possible ways of addressing these disparities are also included.

ItemLearning geometry : Cabri-geometre and the van Hiele levels( 1998)The relationship between the van Hiele levels of learning geometry and pupils' use of the dynamic geometry tool, Cabri-geometre, was investigated using a case study approach. Twelve Year 7/8 students explored aspects of the geometry curriculum using Cabri in conjunction with structured worksheets. Pupils were divided into two groups on the basis of van Hiele pre-tests. Group I comprised students who were at Level 0 or 1, or in transition to Level 2, on most of the concepts: Parallel lines, Rectangles, Right-angled triangles and Isosceles triangles. Group II comprised the remaining students, who were at Level 2 on most of the four concepts. On completion of the worksheets, Group II pupils were required to construct drag-resistant shapes: rectangle, parallelogram, right-angled triangle and isosceles triangle. Following completion of their designated Cabri activities, each student was given a van Hiele post-test. Selected Group H pupils were then given further construction tasks. Students' constructions were documented by means of their saved Cabri files and tape-recorded conversations. The history facility of Cabri enabled the retracing of the students' construction steps. After six lessons for Group I students and seven or eight lessons for Group it students, eleven of the twelve students had progressed a level in two or three concepts. This may be compared with the 20 lessons to take pupils from Level 1 to Level 2, and 50 lessons for progress from Level 2 to Level 3, reported by Dina van Hiele-Geldof. Group II students generally commenced their Cabri constructions by eye but progressed to Level 3 thinking in some constructions. The use of the Cabri menu items enhanced the students' use of appropriate geometric language and there was some evidence that Cabri influenced students' ability to recognise geometric figures in non-standard positions.
